Answer: i'm pretty sure the first option is correct. she wrote it down correctly
(4^9)5 X 4^0
4^9 is 262,144 x 5 = 1,310,720
1,310,720 x 1 = 1,310,720
Answer:880
Step-by-step explanation: They need to cover expense of $13200. If printing fee is $25 and they sell the books for $40 each, then that means when selling a book they cover expense of printing plus they earn $15 per book.
So if they earn $15 per book that means they have to sell 13200/15=880 books to break even.
If you want to solve this by using equation the this would look like this:
expenses: $13200 + $25x where x is number of books sold
earnings: $40x
Equation:
13200+25x=40x
13200=15x
x=880
